WordPress文章自动添加标签链接变为内链

wordpress有一个诟病就是不能自动智能添加标签；当然作为一款国外的开源程序，支持中文智能是有点小纠结的，那我们只能把功能寄托在已经添加过的标签，在发布文章时可以自动为文章添加了。当然如果可以加上一个链接就更好了，好的，那么下面给大家介绍的功能就是自动添加标签及内链的功能代码；只需要把代码复制到主题函数functions.php文件当中，功能就可以实现了

主题的functions.php文件添加如下代码：

area data-settings="dblclick" readonly >$match_num_from = 1;//一篇文章中同一个标签少于几次不自动链接$match_num_to = 1; //一篇文章中同一个标签最多自动链接几次function tag_sort($a, $b){if ( $a->name == $b->name ) return 0;return ( strlen($a->name) > strlen($b->name) ) ? -1 : 1;}function tag_link($content){global $match_num_from,$match_num_to;$posttags = get_the_tags();if ($posttags) {usort($posttags, "tag_sort");foreach($posttags as $tag) {$link = get_tag_link($tag->term_id);$keyword = $tag->name;$cleankeyword = stripslashes($keyword);$url = "<a href=\"$link\" title=\"".str_replace('%s',addcslashes($cleankeyword, '$'),__('【查看含有[%s]标签的文章】'))."\"";$url .= ' target="_blank"';$url .= ">".addcslashes($cleankeyword, '$')."</a>";$limit = rand($match_num_from,$match_num_to);$content = preg_replace( '|(<a[^>]+>)(.*)('.$ex_word.')(.*)(</a[^>]*>)|U'.$case, '$1$2%&&&&&%$4$5', $content);$content = preg_replace( '|(<img)(.*?)('.$ex_word.')(.*?)(>)|U'.$case, '$1$2%&&&&&%$4$5', $content);$cleankeyword = preg_quote($cleankeyword,'\'');$regEx = '\'(?!((<.*?)|(<a.*?)))('. $cleankeyword . ')(?!(([^<>]*?)>)|([^>]*?</a>))\'s' . $case;$content = preg_replace($regEx,$url,$content,$limit);$content = str_replace( '%&&&&&%', stripslashes($ex_word), $content);}}return $content;}add_filter('the_content','tag_link',1);area>1617181920212223242526272829303132$match_num_from = 1;//一篇文章中同一个标签少于几次不自动链接$match_num_to = 1;//一篇文章中同一个标签最多自动链接几次function tag_sort($a, $b){if ( $a->name == $b->name ) return 0;return ( strlen($a->name) > strlen($b->name) ) ? -1 : 1;}function tag_link($content){global $match_num_from,$match_num_to;$posttags = get_the_tags();if ($posttags) {usort($posttags, "tag_sort");foreach($posttags as $tag) {$link = get_tag_link($tag->term_id);$keyword = $tag->name;$cleankeyword = stripslashes($keyword);$url = "<a href=\"$link\" title=\"".str_replace('%s',addcslashes($cleankeyword, '$'),__('【查看含有[%s]标签的文章】'))."\"";$url .= ' target="_blank"';$url .= ">".addcslashes($cleankeyword, '$')."</a>";$limit = rand($match_num_from,$match_num_to);$content = preg_replace( '|(<a[^>]+>)(.*)('.$ex_word.')(.*)(</a[^>]*>)|U'.$case, '$1$2%&&&&&%$4$5', $content);$content = preg_replace( '|(<img)(.*?)('.$ex_word.')(.*?)(>)|U'.$case, '$1$2%&&&&&%$4$5', $content);$cleankeyword = preg_quote($cleankeyword,'\'');$regEx = '\'(?!((<.*?)|(<a.*?)))('. $cleankeyword .
